Shove a 12 in the rear and go with Michelin PSS in 335/30
Does anyone think it would be possible to go that wide in the rear. I doubt it but was just hoping with the corret offsets.

When I pick up my M5 F10 this Spring I was leanings towards 11 rear also but the limited tire options in 305/30 or 315/30 is frustrating. I really love the Michelin PSS. I heard a guy on another forum was considering 315/30 Toyo Proxes on a 11 rear.
